This is a big deal. RDFa allows one to search web pages as if they were databases. Think Google, but with additional options such as: “Show me movies that ...” or “Show me books written by ...” or even “Show me opinions on books written by ...”. With Facebook’s weight behind it, we will hopefully see wider adoption. Publishers that initially support Facebook’s Open Graph standard are IMDb, Microsoft, NHL, Posterous, Rotten Tomatoes, TIME, and Yelp. That already includes quite a bit of useful data. Well, at least as far as movies are concerned.
